and the bottoms of the' wheels-'46being con# siderably'be'low the bottoms of the wheels 16 wheel 16r and one of the: drinn wheels 46v and 40, 42andf44, andthe eable48- runsv around the drumiwheel y17 andone vof the drumV wheels 46 and the other vones of the guide Folding feathering 'impellers 49 conneot 4thecables 47 and 48 Qrosswise at suitable distanoes apart, saidilnpellers being mounted to beopened and pushed the inooinin'gwaves' and' by 'the outgoing' undertow,i 'In otherV words, the impellers'49 faceithefshore onza I line between the upper sides of the wheels 46 s and theupper sides off-fthe Wheels-16 and" 17 and face away from the shore on the return line fromwthe lower faces of the wheels 16 and 17 to the lower faces of the wheels 46. As the cables 47 and 48fare driven by the impellers 49 the wheels 16 and 17 will be rotated to operate the bevel gear 20, drive lthe pinion 24, rotate Vthe shaft 271, and drive the C-ountershaft Y25 to Voperater the driven shaft 28, `and power maybe taken from the driven shaft-28 kin' any suitable way andfor v any desired purpose.l

Each impcller 49 comprises a central plate 50, attaching plates 51 and 52 secured to the ends of the central plate 50, clamps 53 and 54 extending outwardly from the attaching plates 51 and 52 and clamping the cables 47 and 48, a lower wing 55 hinged to the lower edgeof the plate 50, guide fingers Y56 and 57 extending from the ends of the lower wing 55, an upper wing 58 hinged to the upper edge of the plate 50, fingers 59 and 60 extending from the ends of theV upper wing, and chains 61 and 62 connecting the lower wing 55 to the upper wing 58 to limit the spread of the wings.

In the operation of the cables 47 and 48 and the impellers 49 the fingers 56 and 57 will engage upon` the peripheries of the wheels 16 and 17 in making the turn around at the front end of the orbit and the fingers 56, 57, 59 and .60 will engage the cables 47 and 48 to limit the swing of the wings inwardly and the chains 61 and 62 will limit the swing outwardly.

The impellers 49 will fall or feather in going against a current and will unfold when going with the current, provided the current or wave is moving faster than the impellers.

Pairs of pillars 63, 64, 65, 66 and 67 extend upwardly from the pier platform 1 and shafts 68 and 69 are mounted in bearings upon these pillars. Pinions 70 and 71 are fixed upon the shafts 68 and 69 in mesh with the gear racks 11 and l2 upon the sliding bars 9 and 10 and the gear racks 35and 36 upon the sliding bars 31 and 32 and the gear racks upon the sliding bars 43, 45 and 47. vWorm gears 72 and 7 3 are fixed upon the shafts 68 and 69 and a connecting shaft 74 carries worms 75 and 76 in mesh with the gears-72 and 73. A motor 77 is mounted upon the pier platform 1 and connected to the shaft 74 by the chain and sprockets 78, so that as the motor 77 operates, the shafts 68 and 69 will be simultaneously operated to raise or lower the drum wheels 16 and 17, the guide drum wheels 40, 42 and 44, and the drum wheels 46 to raise or lower the cables 47 and 48 carrying the impellers 49. If desired the motor 77 may be an electric motor or a gasolene engine, or the motor may be omitted and the shaft 74 operated manually or in any other desired manner.

Various changes may be made in the details of construction without departing from the spirit of my invention as claimed.

I claim:

' 1. A wave motor comprising piles; a platform mounted upon the piles, said platform extending straight out into the ocean from the shore, and said piles being channelshaped in cross section with the channels the bevel gear upon the drum wheel; a countershaft-mounted upon the platform; bevel gears connecting the countershaft to the drive shaft; said piles being at the land end of the pier; second piles at the ocean end of the pier; drum wheels mounted between the second pair ofpiles; cables running around l the first and second drum wheels; and feathering impellers mounted upon the cables so that theY incoming waves will operate vthe upper impellers and so that the undertow will operate the lower impellers.

2. A wave motor comprising a suitable support v,extending Vfrom a shore into the ocean, bars mounted to slide vertically in the support, gear racks formed upon the inner faces of the bars, means for operating the gear racks to raise and lower the bars, bearings at the lower ends of the-bars, shafts loosely mounted in the bearings, flanged vdrum wheels xed upon the ends of the shafts, a bevel gear upon the outer face of one drum wheel, a drive shaft mounted vertically, a bevel pinion slidingly splined upon the drive shaft in mesh with the bevel gear upon the drum wheel, cables running around the drum wheels, and feathering impellers mounted upon the cables.

In testimony whereof I have signed my name to this specication.
